The KM641001BJ-20 is a static random-access memory (SRAM) device manufactured by Samsung. It's organized as 128K x 8 bits, offering a balance of memory capacity and speed for various embedded and computing applications. Unlike DRAM, SRAM does not require periodic refreshing, making it faster and simpler to use.

Applications

• Cache memory in microcontrollers and embedded processors
• Buffer memory in communication systems
• Data storage in industrial control equipment
• Program storage in programmable logic controllers (PLCs)
• Instrumentation and testing equipment

Features

• Organization: 131,072 x 8 bits
• Fast access time (indicated by -20, though specific value requires datasheet)
• Low power consumption (CMOS technology)
• TTL-compatible inputs and outputs
• Single 5V power supply
• No refresh required

Benefits

• Provides fast and reliable data storage
• Simplifies system design by eliminating the need for refresh circuitry
• Contributes to lower power consumption in portable devices
• Easy to interface with other digital logic components
• Offers a stable and robust memory solution

Additional Details

The KM641001BJ-20 is commonly available in DIP (Dual In-line Package) or SOJ (Small Outline J-lead) packages. The '-20' suffix denotes a specific access time. The 'BJ' likely refers to a specific packaging or feature variant. Refer to the device's datasheet for comprehensive timing characteristics, power consumption figures, and operating conditions. It is suitable for applications where fast access times and ease of use are prioritized over memory density.
